belly; but tlie analogy of L. gumnce, in which the belly 

 varies from nearly pure white to dull greyish buflfy, shows 

 that this character cannot be depended upon in distinguishing 

 members of the present genus. It is possible also that 

 Hensel's ^^ P/n/Uonn/s dasi/thrix^' and Lund's ^^ Phyllomijs 

 hrasiliensis " are also both si)ecifically identical with the 

 Parand form.

Imm. (J. 22iul August, 1901. 



A spinous shoi t-haired species allied to C. spinosus, F. Cuv. 



Spines showing throughout, not hidden by a long clothing 

 of fur. Coat of spines and the fur between them thick and 

 long, far longer than in C. spinosus, the individual spines in 

 the middle of the back ()0 millim. in length or more. 

 Throughout, and especially on the shoulders, there are a few 

 isolated hairs which overtop the spines by about an inch ; on 

 the loins these hairs, although not so long, are more nume- 

 rous. Spines, as usual, white or yellowish white basally, 

 black mesially, and on the back and sides orange terminally ; 

 the proportions of the three colours such that on an average 

 dorsal spine 00 millim. in length al)OUt 30 are white, 18 black, 

 and 12 orange. Spines of face, limbs, and tail tipped with 

 yellowish white instead of orange. Spines of rump, here 

 })arlly hidden by the hairs, bicoloured, white with black tips. 

 Sides of muzzle blackish. Ears quite hidden in the coat, 

 each with a well-maiked tuft of whitish bristles some 

 15 millim. in length. Under surface and inner sides of limbs 

 hairy, grizzled cinereous, the bases of the hairs blackish, 

 their tips whitish, the abundant underfur smoky grey. 

 Upper surface of hands and feet grizzled whitish, with dark 

 bases. Tail witii the middle line of its basal half like the 

 rump, with black- or narrowly white-tipped spines mixed 

 with brownish fur ; sides of basal half spinous, the spines 

 bicolor, with broad whitish tips ; underside of basal half with 

 stity dirty buff bristles ; terminal half naked above, hairy and 

 brown below. 



Skull with the nasals broader and shorter than in C. spi- 

 nosus, very broadly rounded behind. Supraorbital region not 

 inflated, its edges sinuous, with well-detined ridges reaching 

 back on to the anterior third of the parietals. Posterior nares 

 widely open, their edge level with the back of 7h^. Bullae 

 shorter and lower than in C. spinosus. Molars decidedly 

 larijer than those of that animal.
